We just bought one, a 5 door, whitewater pearl in color, with a 5 speed.
like you, we were also considering the matrix, and we damn near bought it... Damn near meaning we were about to sign the dotted line before we decided we should look around a bit more. One of the other cars we looked at was the Mazda 3. Never looked back at the Matrix.
It's a blast to drive. It handles like it is on rails. The ride is a bit harsh, relatively speaking, and with the 5 door, the road noise is a bit loud. For me, those things aren't a major concern; I would rather hear road noise, and feel a bit more of what the car is doing and road contact, then feel isolated from the road like i was on a waterbed. I think that's a preference thing. If you can accept the more "sports car" like feel of the ride, you'll do just fine.
But with the 5 speed it's quick, and the transmission shifts as smooth as silk. It is a very close ratio transmission, like you'd find on a sports car, so when you shift, the engine drops right into mid rpms, right where the power and torque are. this means you go zoom-zoom, but also means you shift a lot sooner. But, the throw on the shifter is miniscule, and there is absolutely NO vagueness in the shifter. Unlike the Matrix, which when I test drove it, I could never quite tell if the transmission was in the right gear or not. With the Mazda, you are completely reassured that the car is in the gear you think it is in. Very solid shifter, not the rubbery vague shifter associated with many cars in the price point. Clutch is abso-fricking-lutely perfect.
the features are good. The interieor materials are a little cheaper feeling, and the doors much lighter than on the Volvo or even the Volkswagen. I would opt for the upgraded Bose stereo system: the stock stereo leaves a little bit to be desired. It's clearly not meant for the kind of music I like, which is NOT hip hop. The stuff I listen to requires more treble and less bass. I don't know for certain, but the stock stereo might be better with some aftermarket speakers.
No problems to report so far. Of course we've had it only 1600 miles. engine is very quiet at idle, but gives a nice reassuring growl when you put your foot on the skinny pedal. So far, we have yet to attain the advertised mileage. I've been averaging about 27 mpg on the highway: of course that figure has to be tempered by the fact that nobody actually drives 55 mph like the mileage figures are calculated.
I also had concerns about long term. I also like to drive cars 15 or more years. This is why I have stuck with Toyota and Volvo all these years. But, I do know several people who own Mazdas, and they have no major issues to report. One friend drove one 285,000 miles before the engine began to show signs of weakness. So I am giving them a chance. At worst, all I need it to do anyway is last 5 years, since that is when we are planning on moving back to Europe. The thing I like about the 3 as opposed to it's big brother the 6, is that the 3 is made fully in Japan of japanese parts, unlike the 6 which is assembled in the USA and probably has a lot more FoMoCo parts. (So far, the only thing I've found on the 3 that says "Ford" is the oil dipstick. Everything else is Denso or other well known Japanese suppliers.
We had wanted a Volvo V50, but since we were paying cash and did not want to go into debt, the Mazda 3 (which is built on the same platform) was a great performer for the amount of cash we had set aside. The Volvo V50 with a T5 and AWD blows the Mazda 3 away in every category: the Mazda doesn't even have a sporting chance. But, The Volvo costs twice as much.... Still, the Mazda 3 is a hell of a lot of car for the money, and it blows the matrix out of the water in the "fun" and looks category.
Let me know of you have any more questions,
Fred
P.S: These cars are not being discounted at all. We were lucky to get a $500 "repeat customer bonus"discount since the local Mazda place is also the local VW place, so we are repeat customers. (but that's just a promotion this particular dealer has, it's not a Mazda program) So, I would expect to pay sticker. The used vehicles are also holding value as well. We had not originally planned on buying new, but when we looked at several used Mazda 3s, we found them to be only $500 to $1000 less than brand new. So, a used car with 25,000 miles and unknown owner and maintenance, or brand new 2006 with 13 miles on the clock for $700 more... Seemed like a no-brainer to me.
P.S.S.: You should also expect to wait. The reason they're not discounting them is because they are selling very well. My wife had to have the Whitewater Pearl Color, and I insisted on the 5-Speed. We again lucked out in that a car that met both criteria was located in the Chicago area (only 1 hour from here) and was dealer traded. We only had to wait a few days. Others at the Mazda3 forum have reported waiting weeks or months till the car was found in the right color/options.
